Real life gets in the way of fantasy life sometimes, little shop time the last month or so, but I finally finished off the passenger and driver side insulation and seat mounts. I purchased sparco seat slider-they latch on both sides and seemed a bit more robust, but with that comes a bit more work. Thanks to Jeff and Dave to give me some insight and tips, especially the spotting bit for drilling, no walking bits for that! Not sure yet If i will like them, they seam nice but they raise the seat almost 2 inches by the time all the stuff is added and the carpet is in....time will tell.

Lay Out:
Minor body fit before I measured out the seat tracks, clearance is tight, having the body on helped locate the seat without interfering. Used Dave's recommendation for this-Inside slider was mounted first along the 4 inch main frame tube, rear hole was offset 3/8 inside center line and front hole was located 3/8 inch outside center line. Both Holes taped for 5/16-24 with out any issues.

I then placed the seat on the tracks (inside bolted down out side not yet drilled) and adjusted seat to clear the body work. this ended up being 1.75 inches inside the seat frame rail, so I measured that up and drilled the seat frame for the inside track mounting. Then drilled the holes on the seat frame for the out side track about 1 inch inside the seat frame, mounted the out side track to the seat frame. This slider required 1/2 clearance from the seat frame to be able to actuate, so I modded the seat from with 1/2 x 1 inch tube, drilled that to match the seat frame. Drilled the holes 1 bit size over to allow for some wiggle to ensure the seat tracks will be parallel after all is done. Passenger side clears the parking brake, but that seat will only be moved for cleaning/access.

With both tracks attached to the seat, I placed the seat in the car and marked and drilled the outer track holes in the floor-rear hole goes thru the 2x2 frame, front hole thru the steel floor.. Critical step here-Make sure the sliders are matching on inside and out. I had an issue with one slider 1 click off the other side and left my hole 1/4 inch off, so I had to drill a new hole in the track to match the floor. With every thing bolted in, and operational, I tac welded the extra frame piece to the seat frame so it would all be 1 piece. I then put a coat of black paint on the seat frame and some expanded PVC in the seat center

Last thing to do was mod the seat latch handle, so I cut the provided piece welded it back together with a little flat plate to ease the operation

And the end result

A lot of work for me with the usually (AAARGH, did I really just do that!), makes the Breeze seat mount look a lot better after that! But they work and hope to go-kart this weekend.
